Greetings,
I want to make shaft taper adapters to hold shafts in a 5C collet on the lathe.
I cleaned up a piece of nylon round stock. I cut off a piece 7/8" long, as this is the grip length on the 5C collet. I drilled it, and now want to bore it with the taper of the cue shaft.
I measured a shaft as 0.510" at the ferrule and 0.825" at the joint fitting, which are 27.3125" apart. According to my calculations this is 0.1384"/ft. taper, which comes out to about 1/3º.
I'm having a tough time setting this up. I'm using the compound rest set to an angle to bore the taper. Of course, the scale on the compound is useless at such a small angle. My dial indicator isn't sensitive enough, and the boring bar not long enough to accurately set it up that way.
There's always trial and error! I guess I could loosen the compound clamp bolts and tap the compound and cut again, trial-fit, and so on. But that could take a lot of time and material.
Any thoughts, other than just buying pre-made taper collect adapters?
